چکیده
|
In this paper, we introduce and solve a system of bi-drygas functional equations{f(x + y, z) + f(x − y, z) = 2f(x, z) + f(y, z) + f(−y,−z)f(x, y + z) + f(x, y − z) = 2f(x, y) + f(x, z) + f(−x,−z)for all x, y, z ∈ x. we will also investigate the hyers-ulam stability of the system of bi-drygas functional equations.
